Carol, where are the porta potties?

亲 所在哪？

Portal can be traced back to the Latin word " porta" , which means gate or entrance.

门户可以追溯到拉丁词“porta”，意思是大门或入。

But in Hannibal's own day, Hannibal ad portas stood for the Roman's genuine terror that their nation was on the ropes, as indeed it was.

但汉尼拔时期，汉尼拔打上门来它代表着罗马人真惧他们国家如履薄冰。
